Rk.: The author's ranking of that pitcher for that day only. T: Pitcher throws left-handed or right-handed. Opp: The pitcher's opponent for the day. QR: "Quality Rating," or the starting pitcher's matchup rating -- separate from the author's ranking -- which accounts for past history (three years' worth as well as past 21 days), opponent and ballpark. OPS is the primary statistic used in the calculation. Ratings range from 1-10, with 10 representing the best possible matchup, statistically speaking, and 1 representing the worst. So, for example, a 10 is a must-start rating, while a 1 should be avoided (if possible); a 1-2 is poor, 3-4 is fair, 5-6 is average, 7-8 is very good and 9-10 is excellent. W-L: Pitcher's win-loss record. ERA: Pitcher's earned run average. WHIP: Pitcher's average number of walks plus hits surrendered per inning.

Editor's Note: Starting pitchers have been updated to account for pitching changes and two doubleheaders

Hitter ratings account for the opposing starting pitcher's past history (three years' worth as well as past 21 days) as well as ballpark factors. "LHB" and "RHB" ratings account only for left- and right-handed batters, respectively. OPS is the primary statistic used in the calculation. Ratings range from 1-10, with 10 representing the best possible matchup, statistically speaking, and 1 representing the worst. So, for example, a 10 is a must-start rating, while a 1 should be avoided (if possible); a 1-2 is poor, 3-4 is fair, 5-6 is average, 7-8 is very good and 9-10 is excellent.

Entering Tuesday, Dustin Pedroia is hitting 32-for-131 (.244) against the A's in his career, 61 points below his career average. Pedroia has been even worse in Oakland-Alameda County Coliseum, hitting just .164 in 55 at-bats.

Current Phillies hitters are just 4-for-18 (.222) against Chris Narveson, with only one extra-base hit and six strikeouts.

The current Marlins lineup is 3-for-28 (.107) with a .219 on-base percentage and .143 slugging percentage against Charlie Morton.

In 44 career games against the Blue Jays entering Tuesday's two-game set, Curtis Granderson has hit just .212 in 187 at-bats, including 1-for-12 (.083) against Brett Cecil

In eight career at-bats against Derek Lowe, Andre Ethier has four hits (.500) including a triple and a home run.
